Perhaps you should try some spelling variations:
"modified parameter optimization algorithmssss" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter optimization algorithmsssss", "modified parameter optimisation algorithmssss", "modified parameter estimation algorithmssss", "modified parameters optimization algorithmssss"
"modified bayesian optimization algorithm" » "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm", "modified bayesian estimation algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified bayesian optimization algorithm") or ("modified parameter optimization algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithm") OR ("modified parameter optimization algorithmssss")).
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithm ) or ( modified parameter optimization algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithm") or ("modified parameter optimization algorithmssss"))*.
